jhipster@4.0 webpack visualstudio代码，找不到chrome调试器源代码

Question

我跟着jhipster安装并且能够运行最新的jhipster。我想使用安装了chrome调试器和低于运行配置的visual studio代码来调试angular2代码

{

"version": "0.2.0",

"configurations": [
    {
        "name": "Launch Chrome against localhost, with sourcemaps",
        "type": "chrome",
        "request": "launch",
        "url": "http://localhost:9000",
        // This forces chrome to run a brand new instance, allowing existing
        // chrome windows to stay open.
        "userDataDir": "${workspaceRoot}/.vscode/chrome",
        "sourceMaps": true,
        "webRoot": "${workspaceRoot}",
        //"diagnosticLogging": true,
        "sourceMapPathOverrides": { "webpack:///C:*":"C:/*" }
    }
]

}

我看到下面的错误和vs代码不会达到调试断点

SourceMaps.loadSourceMapContents：无法从http://localhost:9000/toSubscriber.js.map下载源图...等等

jhipster使用webpack，它不会生成源映射。如何创建这些源地图？
